Description:

Qtractor is an audio/MIDI multi-track sequencer application written in C++ with the Qt framework. Target platform is Linux, where the Jack Audio Connection Kit (JACK) for audio and the Advanced Linux Sound Architecture (ALSA) for MIDI are the main infrastructures to evolve as a fairly-featured Linux desktop audio workstation GUI, specially dedicated to the personal home-studio.

Features:

- Multi-track audio and MIDI sequencing and recording.
- Developed on the Qt C++ application and UI framework.
- Uses JACK for audio and ALSA sequencer for MIDI as multimedia infrastructures.
- Traditional multi-track tape recorder control paradigm.
- Audio file formats support: OGG (via libvorbis), MP3 (via libmad, playback only), WAV, FLAC, AIFF and many, many more (via libsndfile).
- Standard MIDI files support (format 0 and 1).
- Non-destructive, non-linear editing.
- Unlimited number of tracks per session/project.
- Unlimited number of overlapping clips per track.
- XML encoded session/project description files (SDI).
- Point-and-click, multi-select, drag-and-drop interaction (drag, move, drop, cut, copy, paste, paste-repeat, delete, split, merge).
- Unlimited undo/redo.
- Built-in mixer and monitor controls.
- Built-in connection patchbay control and persistence (a-la QjackCtl).
- LADSPA, DSSI, native VST and LV2 plug-ins support.
- Unlimited number of plug-ins per track or bus.
- Plug-in presets, programs and chunk/configurations support, including native VST FXB/FXP file support.
- Unlimited audio/MIDI effect send/return inserts per track or bus.
- Loop-recording/takes.
- Audio/MIDI clip fade-in/out, cross-fade (linear, quadratic, cubic).
- Audio/MIDI clip gain/volume, normalize, export.
- Audio/MIDI track and plugin parameter automation (dynamic curves, sample&hold, linear and spline modes).
- Audio clip time-stretching (WSOLA-like or via librubberband),
pitch-shifting (via librubberband) and seamless sample-rate conversion (via libsamplerate).
- Audio/MIDI track export (mix-down, render, merge, freeze).
- Audio/MIDI metronome bar/beat clicks.
- Unlimited tempo/time-signature map.
- Unlimited location/bar markers.
- MIDI clip editor (matrix/piano roll).
- MIDI instrument definitions (a-la Cakewalk(tm) (*.ins)); SoundFont (*.sf2) and MIDI Names XML (*.midnam) files also supported.
- MIDI controller mapping/learn/assignment (mixer and plug-in parameters).
- MIDI system exclusive (SysEx) setups.
- JACK transport sync master/slave.
- JACK session support.
- NSM (Non Session Management) support.
- MMC control surface enabled.
- MIDI Clock, Song Position Pointer (SPP) support.
- Configurable PC-keyboard and MIDI controller shortcuts.
Last changelog:

0.9.7 2019-04-16 Spring-Break'19 Release. 1 month ago

- Re-defined all main application UNIX signal handling.
- Fixed possible crash in drawing clips while rare loop-recording/takes situations.
- Main window stabilizing is now kind of asynchronous re. menus, tools and status bars.
- MIDI Controller's Latch mode attribute on tracks and plugins are now properly saved/loaded as meant to be.

Thanks for the heads-up on FHS.

Ah,... on so-called "sane" distros (aka not "braindead broken", sorry for the pun) qt3 and qt4 do coexist. And that's what I'm used to. Setting the build environment for each one has been just a matter of PATH tweaking, if one at all. Not a debianese mess, even if its FHS compliant or what. Sorry again :)

Particular problem with Qt deployment on debian seems to be the way that Qt programs, headers, libraries and what not, are kept splintered across the file system. On "sane but FHS broken" distros, all of the Qt tree is usually kept under one single point. Just a minor cost of a particular distro non-standard design ;)

Of course, I should know better that debian guys/gals always know what they're doing :)

Sorry for the twisted humor, and most of all, just plain debian ignorance ;)

Now, back to reality, does it help in any way having this one for a start?

$ ./configure --with-qt=/usr/share/qt4

Just trying... but I'm afraid, due to the way my reasoning works, it should also fail on debian FHS splintering :P

Cheers.

> ./configure --with-qt=/usr/share/qt4

Of course in case of qtractor, where nobody is calling qmake manually, this works, too. Configure then behaves just like with QTDIR=/usr/share/qt4 exported and make will call the *-qt4 executables. Not so different from your distro, is it?

Anyway, despite of the somewhat stressful attitude in this thread, qtractor looks nice.

Thanks ;) now work it. I execute your 3° option: qmake && make.

0.9.7 2019-04-16 Spring-Break'19 Release. 1 month ago

- Re-defined all main application UNIX signal handling.
- Fixed possible crash in drawing clips while rare loop-recording/takes situations.
- Main window stabilizing is now kind of asynchronous re. menus, tools and status bars.
- MIDI Controller's Latch mode attribute on tracks and plugins are now properly saved/loaded as meant to be.

0.9.6 2019-03-20 Pre-LAC2019 Release Frenzy. 2 months ago

- Fixed LV2 UI Touch feature/interface implementation.
- Plugin latency/delay compensation is now introduced as an option to tracks only (cf. Track/Properties.../Latency compensation).
- Refactored all singleton/unique application instance setup logic away from X11/Xcb hackery.
- A bit lesser of a naive file-name numbering is now in place to avoid as much as possible, the piling up of internal curve/automation files when saving existing sessions.
- Maybe just informational but the original MIDI file format is now correctly reported across ref-counted linked MIDI clips.

0.9.5 2019-02-14 A Valentines'19 Hotfix release 3 months ago

- HiDPI display screen support (Qt >= 5.6)
- Fixed for DSSI plug-ins (eg. fluidsynth-dssi) loss of configuration state: clear internal config/state keys on release virtual method.
- Fixed for NSM (and JACK) sessions not saving the correct file references/symlinks of clips that are recorded or created during the initial and scratch session.
